The measure of the exterior angle of the triangle is
O

Measure of exterior angle = 68°

Step-by-step explanation:

By exterior angle property of a triangle.

(7x - 16)°= (x + 8)° + (4x)°

(7x - 16)°= (x + 8 + 4x)°

(7x - 16)° = (5x + 8)°

7x - 16 = 5x + 8

7x - 5x = 8 + 16

2x = 24

x = 24/2

x = 12

Measure of exterior angle

= (7x - 16)°

=(7*12 - 16)°

= (84 - 16)°

Measure of exterior angle = 68°

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
